*
* The crafted metafile (WMF) from this code when viewed in explorer crashes it. The issue is seen
* when the field 'mtNoObjects' in the Metafile header is set to 0x0000.
* The code was tested on Windows 2000 server SP4. The issue does not occur with the
* hotfix for GDI (MS05-053) installed.
*
* Disclaimer: This code is for educational/testing purposes by authorized persons on
* networks/systems setup for such a purpose. The author of this code shall not bear
* any responsibility for any damage caused by using this code.
